Even if being busy with solar power, electric cars, reusable space rockets and colonizing Mars as we can't even begin to imagine, Elon Musk managed to launch another company.
Neuralink Corp. is an American bio- and nanotechnology startup that will be developing implantable brain–computer interfaces (BCI). Even though it was actually quitely launched in 2016, it didn't make any noticable news until March 2017.
The technology that's being worked on at Neuralink is called the "neural lace" technology. It is supposed to allow people to merge and communicate with the machines without any physical interface that we use today, which is to be achieved by implanting tiny electrodes in the human brain. Imagine having no need for a phone anymore to access internet while on the go - imagine just thinking about finding some online information and the search begins with results instantly appearing in your brain.
The potential is endless, albeit scary and will probably lead to many heated debates, including to the eternal philosophical question - what makes us human, really? Where is the line between AI and human intelligence? Musk hasn't disppointed so far, so whatever it is that he is planning to do, will most likely be, again, groundbreaking.
While information is scarce at the moment, some news will soon be available. On March 28, Elon Musk tweeted: "Long Neuralink piece coming out on @waitbutwhy in about a week. Difficult to dedicate the time, but existential risk is too high not to."
